1 Claim.

The present invention relates to new and use- Other objects of the invention are to provide; a ventilating apparatus of the aforementioned character which will be comparatively simple inconstruction, strong, durable, highly efiicient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation of a ventilating apparatus constructed in accordance with the present invention, showing the window closure or panel in cross-section.

Figure 2 is a top plan view of a portion of the apparatus.

Figure 3 is a cross-sectional view, taken substantially on the. line 3-3 of Figure 1.

Figure 4 is a perspective view of the adjustable window panel.

Figure 5 is a fragmentary view in vertical longitudinal section, taken substantially on the line 5-5 of Figure 2.

Figure 6 is a fragmentary view in vertical Ion} gitudinal section, taken substantially on the line 6-45 of Figure 2.

Figure '7 is a view in side elevation, showing a slight modification.

Referring now to the drawings in detail,

Connected to the fan I is a conduit which is designated generally by the reference numeral '4, The conduit 4 includes a reducer 5 which is secured to the outlet 6 of the fan I. Secured byfa split collar or clamp I to the small end portion 8 of the reducer 5 is a nipple 9. The conduit 4 further includes a tube 10 whic may be of any suitable flexible material and which has one end portion secured on the niople 9. The other end portion of the flexible tube In is secured to a nipple II which, in turn, is connected to one end of an adjustable elbow I2 through the medium of a split collar or clamp IS. A rivet l4 (see Fig. 5) secures the clamp Hi to the elbow l2.

The other end portion of the elbow I2 is connected to one end portion of an adjustable elbow. 15. The other end portion of the elbow I5 is secured, as at iii, in one end portion of a relatively short pipe section 11 which is mounted in a window panel l8.

The end portions of the nipples 9 and H which receive the flexible tube Ill have pressed therein circumferential grooves or channel I9. The end portions of the flexible tube it) are cemented to the nipples 9 and II and are further secured by wire bands 20 which the grooves or channels l9 receive. This is shown to advantage in Figures 5 and 6 of the drawings,

The panel I8 is adjustable for mounting in windows of different widths. Toward this end, the panel l8 includes a pair of1slidab1y connected section 2| and 22. The upper and lower edges of the section 2| are provided with guides 23 in which the section 22 is slidable. A handle 24 is provided on the panel section 22. The pipe section I! is mounted in the panel section 2|.

It is thought that the manner in which the apparatus functions will be readily apparent from a consideration of the foregoing. Briefly, with the fan I in operation paint and other fumes are drawn thereinto and expelled from the room or other enclosure to the outside atmosphere through the conduit 4. The construction and arrangement of the conduit 4 is such as to permit the fan unit to be placed in substantially any desired position relative to the window in which the adjustable panel I8 is mounted. In Figure 1 of the drawings, reference numeral 25 designates generally a portion of a conventional window comprising a vertically slidable lower sash 26. The panel I8 is placed on the sill 21 of the window 25 and adjusted so that the ends of said panel engage the vertical sides of the window frame. The sash 26 is then lowered into engagement with the panel l8, thus closing the window opening.

In Figure 7 of the drawings, reference numeral 28 designates a single depending adjustable elbow which is secured to the inner end portion of the pipe section II. A vertical nipple 29 is secured by a split collar or clamp 30 in the lower end portion of the elbow 28. Then, the flexible tube I0 is secured to one end portion of the nipple 29.

It is believed that the many advantages of a ventilating apparatus constructed in accordance with the present invention will be readily underdow opening and having a main section and an auxiliary section, a pipe section extending through the main section of said panel, a flexible conduit, a coupling extending from the inner end of said conduit, a clamp detachably securing said coupling to the outer end of said reducer, a nipple extending from the outer end of said flexible conduit, a pair of rotatably connected elbows, the outer one of said elbows being secured to the inner end of the pipe section, and a clamp secured about the inner elbow for detachably securing the same about the nipple at the outer end of said conduit.
